Nettet20. sep. 2024 · How does a loud speaker work GCSE physics? Inside a loudspeaker, there is alternating current which passes through coil which is wrapped around a magnet. There’s a second wire with a separate current passing through it. The two magnetic fields created interact, causing force to be exerted. Nettet(c) The figure below shows the parts of a moving-coil loudspeaker. A coil of wire is positioned in the gap between the north and south poles of the cylindrical magnet. …

Nettet12. mar. 2024 · The center of the speaker cone is attached to one end, which gets driven back and forth by the moving coil. This cone is held at its edges by an airtight suspension or surround. As the cone moves, it pushes and pulls the surrounding air; by doing so it creates pressure waves in the air, called sound. So that’s how the speaker driver works ...

NettetTape or glue the magnets onto the wooden blocks (not shown in the diagram) to keep them at the right height, then move the blocks to put them in position, rather close to the coil. Rotate the coil initially so that the magnetic flux through the coil is zero, as shown in the diagram. Now get a battery, and two wires with crocodile clips.
Nettet• increase the number of coils in the wire; • increase the current passing through the wire. An electromagnet is a solenoid with an iron core. Electromagnets are induced magnets and can be turned on and off. Electric motors, loudspeakers, electric bells and remotely controlled door locks all use electromagnets. python m3u8 key ivNettet5. apr. 2024 · zip, 35.85 MB A fully resourced lesson designed for the new AQA GCSE specification, from an experienced author.
